ICD-10 Code H83.03 – Labyrinthitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.03 – Labyrinthitis, bilateral
What it is
H83.03 identifies inflammation of both inner ears’ labyrinths. Use it when documentation specifically states bilateral labyrinthitis, a condition that can affect balance and hearing.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include vertigo, nausea, imbalance, and hearing symptoms when the labyrinth is involved.
When to use this code
Use H83.03 when the provider documents labyrinthitis affecting both sides, or clearly describes bilateral inner ear inflammation. Apply it only when the bilateral nature is stated or can be supported by the note.
Do not use for
Do not use this code for unilateral labyrinthitis, nonspecific dizziness, or vestibular disorders without labyrinth inflammation. Check documentation if laterality is unclear.
Coding tip
If the record says only “labyrinthitis,” query for laterality before assigning a bilateral code.
